memory: add ARM PL172 MultiPort Memory Controller driver This driver makes it possible to configure the static memory chip selects on the ARM PL172 MultiPort Memory Controller from a set of properties in DT. Configuration of dynamic memory is not supported and is left to the boot loader. The intended usage is to setup timing and configuration for static memory devices like NAND and NOR Flash before they are probed by a driver.

memory: add Atmel EBI (External Bus Interface) driver The EBI (External Bus Interface) is used to access external peripherals (NOR, SRAM, NAND, and other specific devices like ethernet controllers). Each device is assigned a CS line and an address range and can have its own configuration (timings, access mode, bus width, ...). This driver provides a generic DT binding to configure a device according to its requirements. For specific device controllers (like the NAND one) the SMC timings should be configured by the controller driver through the matrix and smc syscon regmaps.

drivers: memory: Introduce Marvell EBU Device Bus driver Marvell EBU SoCs such as Armada 370/XP, Orion5x (88f5xxx) and Discovery (mv78xx0) supports a Device Bus controller to access several kinds of memories and I/O devices (NOR, NAND, SRAM, FPGA). This commit adds a driver to handle this controller. So far only Armada 370, Armada XP and Discovery SoCs are supported. The driver must be registered through a device tree node; as explained in the binding document. For each child node in the device tree, this driver will: * set timing parameters * register a child device * setup an address decoding window, using the mbus driver Keep in mind the address decoding window setup is only a temporary hack. This code will be removed from this devbus driver as soon as a proper device tree binding for the mbus driver is added.

memory: Add NVIDIA Tegra memory controller support The memory controller on NVIDIA Tegra exposes various knobs that can be used to tune the behaviour of the clients attached to it. Currently this driver sets up the latency allowance registers to the HW defaults. Eventually an API should be exported by this driver (via a custom API or a generic subsystem) to allow clients to register latency requirements. This driver also registers an IOMMU (SMMU) that's implemented by the memory controller. It is supported on Tegra30, Tegra114 and Tegra124 currently. Tegra20 has a GART instead. The Tegra SMMU operates on memory clients and SWGROUPs. A memory client is a unidirectional, special-purpose DMA master. A SWGROUP represents a set of memory clients that form a logical functional unit corresponding to a single device. Typically a device has two clients: one client for read transactions and one client for write transactions, but there are also devices that have only read clients, but many of them (such as the display controllers). Because there is no 1:1 relationship between memory clients and devices the driver keeps a table of memory clients and the SWGROUPs that they belong to per SoC. Note that this is an exception and due to the fact that the SMMU is tightly integrated with the rest of the Tegra SoC. The use of these tables is discouraged in drivers for generic IOMMU devices such as the ARM SMMU because the same IOMMU could be used in any number of SoCs and keeping such tables for each SoC would not scale.
